WILLIAM E. WOODARD, OF LIMA, OHIO.

OUTSIDE-OPERATED TANK-VALVE.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed November 6, 1917. Serial No. 200,511.

I T all whom it may concern:

Be it known that I. VILLIAM E. Woonann, a citizen of the United States, residing at Lima in the county of Allen-and State of Ohio. have invented certain new and useful Improvements in Outside-Operated Tank.- Valves, of which the following is a specification.

This invention relates to improvements in tank valves such as used for example on locomotive tenders. i

In general the invention relates to that class of tank valves shown in United States Letters Patent, #1..20+l,108 issued to me on .\'ovembe1"7th. 1916. and the present improvement consists in the simplification of the structure, the reduction of the number of pieces which contain the tank valve and form the connection to the tank. and also in an arrangement of the parts whereby the interior strainer maybe placed in position inside the tank, or removed therefrom through the tank well opening. The invention also contemplates certain specific improvements hereinafter to' be pointed out.

I obtain the foregoing by means of a con' struction which I have illustrated in pre ferred form in the accompanying drawings. wherein Figure 1 is a side elevation, partly in section, of my improved valve. with its application to a tank indicated diagrannnatically; Fig. 2 is a top plan of Fig. 1; Fig. 3 is a partial end elevation and section of Fig. 1; and Fig. 4 is a sect-ion taken on the line T"IV of Fig.

lu practically all forms of-tank valves now in use, the prin'iary strainer which prevents coal, pieces of wood. leaves. etc. from clogging th valve. has been applied inside of the tank in such manner that to clean or remove it, it is necessary. to enter the tank. Since such tank strainers often become clogged. they must be periodically cleaned, which is an 0)81't1tl011 involving considerable time and expense. As hcreinhefore pointed out. it is one of the primary obp .s of my invention to provide a valve of this tnaracter in which the primary strainer can be inserted or removed. for purposes of cleaning or replacement. from the exterior ofthe tank. in a simple and expeditious manner, and at small expense.

In carrying out my invention 1 divide the tank valve structure into two main parts, namely, the valve casing '2' and the tank well 8. The tank well is secured to the tank wall 9 in any preferred manner, and the valve 10. the operating shaft 11 therefor. and the lower or secondary strainer 12, are all mounted in the casing 7, such casing being also provided with the usual outlet means 18 for making connections to the feed water system. 7

The casing 7 is hinged to the tank well 8 in the manner indicated at 14, and it is held in operative position by means of a pair of oppositely disposed bolts 15 supported from the tank well. as by the pivotal arrangement indicated at 16. in Fig. 1.. The lower end of the bolts are adapted to be passed between pairs of spaced lugs or ears 17 formed on the casing T. the casing being drawn tightly against its seat on the tank well by means of the nuts 18. in a manner that will be readily understood from an inspection of the drawings. The nuts 18 are locked by the l)(l nuts 19.

The main or primary strainer 20 is adapted to be entered into the opening in the tank well and is positioned with respect to the tank well and the valve by means of a plurality of small angle plates or clips 21 adapted to be held between the annular lip 22 of the tank well and the top of the casing 7, when the casing is secured to position. as indicated in Fig. 3. Q After the .tank well has been secured to the tank proper, and the interior strainer 20 entered, the casing 7 is swung into the position shown in Fig. 3, and drawn tightly against its seat by the bolts 15 in the manner described. The interior strainer is now securely held in place, covering the valve. \Vhen the interior strainer becomes clogged. it is only necessary to break the feed pipe connections to the tank valve, loosen the bolts holding the lower casing 7 t0 the tank well, and then swing the casing backward and out of. line with the direct opening into the tank. which allows the interior strainer to drop. The tank can then be flushed out through the large opening of the tank well and the debris removed after which the operation is reversed and the device is ready for re-use when the feed waterconneetions have been made.

It will be seen from the foregoing that the arrangement is such that the parts can be easily assembled'and the interior strainer expeditiously removed and cleaned and re placed. The mounting of the valve 10, its

lit)

operatingmechanism, and the secondary strainer 12 in one casing is advantageous not only because of the inherent simplicity of the arrangement but also because such arrangement obviates any difficulties which might otherwise be incident to the removal and cleaning of the primary strainer, were certain of the parts mounted on the tank well. p

It will be obvious that my invention is not limited to the precise arrangement shown, and that modification can be made without departing from the spirit of the invention.

I claim:

1. A tank valve mechanism comprising valvular means adapted to be releasably attached adjacent the tank opening, and a strainer adapted to be entered into said opening and covering the valve, said strainer being positioned by the valvular means when attached.

2. A tank valve mechanism comprising in combination a tank well adapted to be secured adjacent the tank opening, valve means pivotally attached to said tank well at one side of the opening and adapted to be swung to one Side thereof, and a strainer adapted to be entered into said opening and covering the 'alv'e said strainer being positioned by the valve means when swung into position over said openin 3. A tank valve adapted to be attached adjacent the tank opening, a strainer adapted to be inserted from the exterior intov said tank opening and covering the Valve, and means for lnngmg said valve to the tank and one side of said opening. v

5. A tank valve mechanism oomprlsing la combination valve mechanism mounted adjacent a tank opening for movement into and out of the km of said opening, and a strainer adapted to be inserted into said opening and covering the valve mechanism,

said strainer being adapted to be withdrawn.

upon movement of the valve means out of the line of said opening.

In testimony whereof I have hereunto signed my name.

\VILLIAM E. WVOODARD.
